4. Queen - We Will Rock You
https://www.youtube.com/watch?v=-tJYN-eG1zk Go to any sports stadium in the world and there's a good chance the 'stomp,stomp, clap' of 'We Will Rock You' is echoing throughout the arena, with fans often screaming the words along. One of Queen's most famous songs, it was released as the B-side to another Queen smash hit 'We Are The Champions'. The song could be found on the band's 1977 album News of the World, but was never released as its own single. In 2000, UK boyband Five released a cover of the song; it reached number 1 in the UK. It's an example of how a song can capture a generation and then gain its own popularity,with or without a single release.
